Commercial real estate transactions involve complexity and risk that residential transactions rarely approach. The purchase of a commercial property is simultaneously a real estate transaction, a business decision, and a regulatory compliance exercise. Each due diligence item exists because someone, somewhere, purchased a property without investigating it and suffered consequences that made the lesson memorable. Title Examination and Survey The title examination for a commercial property is more involved than its residential counterpart. Commercial properties frequently have easements, restrictive covenants, shared access agreements, and other encumbrances that affect how the property can be used. A thorough title examination identifies these encumbrances and evaluates whether they are consistent with your intended use. A current ALTA survey should be obtained for any commercial acquisition. The survey identifies the exact boundaries of the property, the location of improvements, encroachments (where structures cross property lines), easements, setback lines, and flood zone designations. Discrepancies between the survey and the title report often reveal issues that require resolution before closing. Title insurance for commercial transactions typically involves negotiation over the scope of coverage. Standard policy exceptions for survey matters, mechanics' liens, and environmental contamination can often be removed or narrowed through additional due diligence and negotiation with the title company. Environmental Assessment Environmental due diligence is non-negotiable for commercial property acquisitions. Under federal environmental law (CERCLA), the current owner of contaminated property can be held liable for cleanup costs regardless of whether they caused the contamination. The innocent landowner defense requires, among other things, that the buyer conducted "all appropriate inquiries" before acquisition. A Phase I Environmental Site Assessment, conducted in accordance with ASTM standards, evaluates the property's history and current conditions to identify recognized environmental conditions. The assessment includes a review of historical records, regulatory databases, aerial photographs, and a physical inspection of the property and surrounding area. If the Phase I assessment identifies recognized environmental conditions, a Phase II assessment involving soil and groundwater sampling may be warranted. The cost of a Phase II assessment is significant, but it is trivial compared to the cost of remediating contaminated soil or groundwater after acquisition. Zoning and Land Use Verification Zoning verification confirms that your intended use of the property is permitted under the applicable zoning ordinance. This analysis goes beyond simply checking the zoning classification. It includes verifying that the property's current use is a permitted use (not merely a nonconforming use that could be lost), confirming compliance with parking requirements, reviewing any conditional use permits or variances, and evaluating pending zoning changes that could affect the property. Many commercial properties operate under nonconforming use status, meaning the current use was legal when established but would not be permitted under current zoning. Nonconforming uses are typically protected as long as the use is not abandoned or significantly changed. Understanding these limitations before acquisition is essential. Building and Code Compliance A commercial building inspection should be conducted by professionals experienced with commercial structures. The inspection should cover structural systems, roofing, HVAC, plumbing, electrical systems, fire suppression, elevator systems, and ADA accessibility compliance. Code compliance is a particular concern for older commercial buildings. Many buildings constructed before the adoption of current building codes, fire codes, and accessibility requirements may have grandfathered compliance. Significant renovations can trigger requirements to bring the entire building into current code compliance, which can be extraordinarily expensive. Lease and Tenant Analysis If the property is income-producing, the leases are among the most important documents in the transaction. Every lease should be reviewed for its term, renewal options, rent escalation provisions, tenant improvement obligations, maintenance responsibilities, assignment and subletting rights, co-tenancy clauses, and termination rights. Estoppel certificates should be obtained from each tenant confirming the lease terms, any outstanding obligations of the landlord, and any disputes. Tenant financial strength should be evaluated, particularly for properties where a single tenant represents a significant percentage of rental income. Financial Analysis The financial due diligence for a commercial property goes beyond reviewing the seller's income and expense statements. Operating expenses should be verified against actual invoices
